Their application spans dental clinical fields in both Japan and the US. Nonetheless, owing to the granular nature of CO₃Ap, certain challenges in the application of these materials can arise, such as intraoperative scattering and postoperative migration. To address these issues, we integrated CO₃Ap granules with collagen to generate a sponge-like composite. Collagen, typically derived from bovine or porcine sources, is commonly utilized in clinical settings despite the potential for infections, including parasitic zoonosis. For the purposes of this study, we selected fish-derived collagen (FC), which minimizes the risk of zoonotic complications. Compared with CO₃Ap-G, the CO₃Ap granule/FC composites (CO₃Ap-G/FCs) fabricated in this study were characterized by an enhanced handling performance. Bone regeneration ability was assessed by implanting these composites into critical-size defects in rat calvarial bones for 2–4 weeks using CO₃Ap-G and FC as controls. Radiographic and histological examinations revealed that the bone-regenerative capacity of CO₃Ap-G/FCs was equivalent to that of CO₃Ap-G. We accordingly conclude that sponge-like CO₃Ap-G/FC composites have potential utility as ideal bone substitutes, in that they can be manipulated with forceps, bent, and cut with scissors, without losing the bone-regenerative properties of CO₃Ap-G.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":647,"journal":{"name":"Journal of Materials Science: Materials in Medicine","volume":"36 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12174302/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RGO@PDA was synthesized through a 12-h magnetic stirring process of graphene oxide and dopamine at room temperature. This water-dispersible and biocompatible compound demonstrated remarkable efficacy in enhancing osteogenic differentiation in rat bone mesenchymal stem cells (rBMSCs), evidenced by increased alkaline phosphatase activity, mineralization, and the upregulation of osteogenic genes and proteins. Furthermore, RGO@PDA showed significant capabilities in scavenging reactive oxygen species (ROS) and reducing proinflammatory factor expression.

The investigated materials include pure PLA, a PLA composite containing gypsum, and a clinically approved resin material. Strength and hardness tests were conducted using custom-made samples measuring 16 × 4 × 2 mm³. Additionally, oral cavity scans were used to generate oral models for each material to assess their accuracy, trueness, and precision. The results indicated that pure PLA exhibited the highest flexural modulus (2055 ± 217.70 MPa) and compression modulus (2.40 ± 0.14 GPa). The PLA-Gypsum composite displayed the highest hardness (19.48 ± 2.12 HV1). As for the trueness of the oral models, there were no statistically significant differences between the models made from the three materials. However, the PLA-Gypsum composite demonstrated the best precision (23.84 ± 4.12 μm).

Porcine cornea has been receiving increasing attention due to its ease of obtaining, biomechanical properties similar to those of human tissue and lower antigenicity. Based on this, the objective of this study was to evaluate the biocompatibility of porcine stroma decellularized by sodium dodecyl sulfate (SDS) through interlamellar implantation in rabbit corneas. The obtained results showed that the lenticule intrastromal implantation was successfully performed and did not elicit rejection. Furthermore, the implanted stroma was able to promote an increase in the thickness of the host cornea. Microscopic analyses revealed that the tissue was well-adhered and the collagen fibrils were more aligned on its periphery. Therefore, it is concluded that the implantation of decellularized porcine stroma occurred satisfactorily and represents a promising alternative to replace human tissue.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":647,"journal":{"name":"Journal of Materials Science: Materials in Medicine","volume":"36 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12148985/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sodium alginate (SA) has attractive properties of biocompatibility, biodegradability, which have been exploited to be natural-origin polymer of drug release. Because of special egg box structure of SA, the sodium ions in the structure can be exchanged with divalent cations through crosslinking, which could control the pore size inside the material and release rate of the loaded drug. Here, we utilized the composite of sodium alginate and polyethylene oxide (PEO) with natamycin loaded through crosslinking with calcium ion ethanol aqueous solution to delay drug release and treat fungal keratitis.

The cytotoxicity, cell proliferation inhibition, endocytosis pathway, intracellular trafficking/localization, and autophagy behavior of the blank glycopolymer micelles and/or DOX-loaded micelles were studied in a Human Glioblastoma Carcinoma (H4) and green fluorescent protein-tagged H4-GFP-LC3 cell lines. The glycopolymer micelles could be taken up into the cells through favorable caveolae-mediated and clathrin-mediated endocytic pathways, and their intracellular trafficking/localization were associated with endosome-lysosome systems. Notably, after treating with DOX-loaded glycopolymer micelles (or free DOX) to the H4-GFP-LC3 cells, exogenous substances-induced autophagosome accumulation was observed. The autophagy inhibitors: 3-methyladenine (3-MA) and hydroxychloroquine (HCQ) were used to monitor the autophagy behavior of H4-GFP-LC3 cells incubated with the micelles. Interestingly, the autophagy inhibitors could significantly enhance the antitumor performance of the free DOX and/or DOX-loaded micelles, the drug combination effect of autophagy inhibitors and DOX was further studied by Bliss independent model analysis. Taken together, this work provided a preliminary understanding of the intracellular drug delivery properties of glycopolymer micelles and demonstrated the effect of different autophagy inhibitors, which might inspire future innovation of “autophagy regulator-combined nanotherapeutics” toward efficient cancer chemotherapy.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":647,"journal":{"name":"Journal of Materials Science: Materials in Medicine","volume":"36 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12144062/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
